CMS-3646-18SP

Speakers Overview

The CMS-3646-18SP is a miniature round speaker manufactured by Same Sky. It features a 36 mm diameter and a depth of 4.6 mm. The unit utilizes a PET diaphragm and a neodymium magnet for acoustic performance. It has an impedance of 8 ohms and a power rating of 1 W. The resonant frequency is specified at 580 Hz. Electrical connections are provided via solder pads rather than wire leads.

Speakers Feature Summary

• Compact circular design with a 36 mm diameter and 4.6 mm depth suitable for space-constrained enclosures.
• Utilizes a PET diaphragm material combined with a neodymium magnet to ensure efficient sound reproduction.
• Equipped with surface-mount solder pads for direct PCB integration without the need for additional wiring harnesses.

Speakers Applications

• Consumer electronics requiring compact audio output
• Industrial control panels needing small form factor speakers
• Medical devices with limited internal volume

Speakers Procurement Notes

Verify the specific suffix SP indicates solder pad termination when comparing against wire-lead variants. Confirm the operating temperature range and acoustic specifications match the target application requirements before finalizing the order. Ensure PCB layout accommodates the solder pad footprint dimensions accurately.

Speakers Selection Notes

Select this model when a low-profile, round speaker is required for board-level assembly. The 8-ohm impedance matches standard amplifier outputs. Consider the 1 W power handling capability relative to the desired sound pressure level. The PET diaphragm offers durability in typical indoor environments.

Speakers Part Context

This component belongs to the Same Sky miniature speaker series designed for embedded audio applications. It represents a transition from traditional wire-lead designs to surface-mount compatible formats. The product line emphasizes high acoustic efficiency within minimal physical envelopes for modern electronic device integration.

Speakers Replacement Considerations

The CMS-3646-18S is a related variant featuring wire leads instead of solder pads. Verify mechanical mounting constraints and electrical connection methods when substituting between these two models to ensure compatibility with the existing circuit board design.
